3.6 Parameter setting groups

3.6.2 Functionality
The protection relay supports six setting groups. Each setting group contains
parameters categorized as group settings inside application functions. The
customer can change the active setting group at run time.
The active setting group can be changed by a parameter or via binary inputs
depending on the mode selected with the Configuration> Setting Group> SG
operation mode setting.
The default value of all inputs is FALSE, which makes it possible to use only the
required number of inputs and leave the rest disconnected. The setting group
selection is not dependent on the SG_x_ACT outputs.
Table 35: Optional operation modes for setting group selection
SG operation mode Description
Operator (Default) Setting group can be changed with the setting Settings> Setting
group> Active group.
Value of the SG_LOGIC_SEL output is FALSE.
Logic mode 1 Setting group can be changed with binary inputs
( BI_SG_2...BI_SG_6). The highest TRUE binary input defines the
active setting group.
Value of the SG_LOGIC_SEL output is TRUE.
Logic mode 2
Setting group can be changed with binary inputs where BI_SG_4 is
used for selecting setting groups 1-3 or 4-6.
When binary input BI_SG_4 is FALSE, setting groups 1-3 are selec-
ted with binary inputs BI_SG_2 and BI_SG_3. When binary input
BI_SG_4 is TRUE, setting groups 4-6 are selected with binary inputs
BI_SG_5 and BI_SG_6.
Value of the SG_LOGIC_SEL output is TRUE.
The setting group (SG) is changed whenever switching the
SG operation
mode
setting from "Operator" to either "Logic mode 1" or "Logic mode 2."
Thus, it is recommended to select the preferred operation mode at the
